一、安装本地Maven选择你需要的maven版本下载：官网下载传送门
这里推荐使用3.6.1版本

二、安装把下载好的maven压缩包解压到一个没有中文，空格或其他特殊字符的文件夹，如：

三、配置环境变量
右键 此电脑-&gt;属性-&gt;高级系统设置-&gt;环境变量


\2. 新建系统变量MAVEN_HOME


编辑系统变量Path，添加变量值%MAVEN_HOME%\bin

1%MAVEN_HOME%/bin

4.验证安装是否成功，win+R运行cmd，输入mvn -v，如图所示则配置成功

四、配置settings文件
在Maven安装目录conf目录下找到settings.xml配置文件




修改本地仓库地址（1）在maven安装目录下新建本地仓库文件夹maven_repository


（2）修改默认本地仓库地址


配置私服，因为中央仓库在国外导致下载jar包很慢或者失败，所以我们改为国内的服务器，下面三个选择一个就可以了。

2. 关系型数据库关系型数据库模型就是把复杂的数据结构归结于简单的二元关系（即二维表格形式）。在关系数据库中，对数据的操作几乎全部建立在一个或多个关系表格上，通过这些关联表的表格分类，合并，连接或选取等运算来实现数据的管理。
SQLSQL就是结构化查询语言
用于从数据库中有结构的查询
NoSQL（非关系型数据库）NoSQL，泛指非关系型数据库
MySQL相关命令

2. CRUD1. 表的结构1.1 表名一般使用英文小写字母来约定表，多个单词之间使用_分隔
1.2 主键
主键是一个特殊字段
表格可以没有主键，但最多只能拥有一个主键
主键的值不能为NULL ，必须有对应的值
主键的值必须绝对唯一的，即不能出现两个相同的主键值，如名字就不可以作为主键，因为会有重名
一般使用主键和其他表进行关联
